BALBBITTING APPARATUS.

Patented Feb. 24, 1920.

Application filed July. 11, 1919. Serial No. 310,110.

will enable others skilled in the art to which it pertains to make,construct, and use the same, reference being had to the accompanyand tonumerals of'reference ing drawings 7 forming a part of this markedthereon, specification.

My invention relates to machines for east ing small articles of variouskinds and classes of metal, as for instance, for applying Babbittmetal'to engine connecting rods; and the object thereof is to provide animproved machine of this class which is simple in construction andeflicient in operation,

and which may be conveniently manipu- 'lated.

The primary objectof my invention is to taketlie usual connecting rodhaving a wrist pin bearing at one end thereof and a crank pin bearingbox at the other end, said crank pin bearing box usually comprising twohalves the former of which is integral with the rod, and the latter ofwhich is separate and may be attached to the former by bolts extendingthrough both and retained in place by nuts, and to cast a Babbittbearing in the crank pin bearing box which will not be spongy or porous,but possessed of the requisite density.

WVitli these and other objects inview the invention consists in noveldetails of construction and combination of parts more any hereinafterdisclosed and particularly pointed, out in the claims,it being undertheprecise embodiment of the invention herein disclosed can withoutdeparting from the spirit of invention.

The invention has'been illustrated in its preferred embodiment in theaccompanying drawings; wherein: p V 1 Figure 1 represents, alongitudinal section of the upperand lower divided dies with the core inposition and showing in dotted lines a connecting rod clamped inoperatlve position between the said upperand lower divided'di'es.

Figs. 6 and 7 represent, respectively, end and side elevations ,of thecompletedbabbitte'd bearing removed -.-r1-0m the connecting rod.

Fig. 8 represents, a side elevation of the .babbittedbearin'g as itleaves the divided dies, and shown removed from the connect- 7 ing rod.V

1g. 9 represents, an end view of said bearing looking in the directionindicated by the arrow in Fig 8. p Fig. 10 represents, a transversesection taken on line mm of Fig. 8, and looking in the dlrection of thearrow; and

Figs. llqand 12 represent, respectively,

side elevation and an end view ofthe core used in connection with thedivided dies.

Similar characters of reference are shown in all of the above describedviews, to indicate corresponding parts. i r

In the drawings 1' represents the upper divided die;.2 represents thelower divided die and 3 represents the core which is movablysecured tothe platen 4 to which thegupper die 1 is secured, and which engageswithboth the upper and lower dies as. clearly illustrated in- Figpl of thedrawings.

The dies 1 and 2 are connected in the usual 'manneras is common in diepasting machines so that the two dies and'core can be brought to etherin the positionillustrated 1 he drawings with the recessed portion 6, inthe undersideof the platen 5,

fitting over the outlet of the cylinder containing the molten metal, notshown.

The molten metal, as is-comnion, passes "from the outletof the cylindercontaining the same into the diametrically, oppositely 7 and 8 whiehare, arranged one in each section 18of the divided there is forcedupward througlrsaid die around the core 3 into the crank pin bearing boxof the connecting rod 9 illustrated indotted lines in Fig. l of thedrawings, and'tlience upwardly into the die produced possessing thehighest degree of density and one that will not be spongy or porous. V

The upper divided die 1 consists of the two sections l0 fitted intosuitable gibs 11-11 secured to the under side of the platen 4, and isprovided with the cylindrical aperture 12 and a series of steppedportions 13l313 designed to receive the .cylindrical portion 14 and thestepped portions 1515l5 of the core 3.

The apertured portion 12 of the die 1 is further provided withpreferably four pads 16 which'contact with the part 14 of the core 3 andwhich form the vents 17 of'the babbitted bearing illustrated in Fig. 8-of the drawings.

. The lower divided die 2 consists of two sections18-18 fittedinto'suitable gibs 20 secured to the upper side of the platen '5,

the central portions of the sections 1818 are recessed to receive thecore 19, which is secured to the platen 5 in any desired or convenientmanner. 7

In each section 18 of the lower die 2 passage ways 7 and 8 are formed topermit the molten metal to be forced, from the cylinder containing thesame, into the said passage ways and up around the cylindrical portion21'0f the core 3. V

The end of the core 3' adjacent to the cylindrical portion 21 isprovided with a projection 22 designed to be received into the aperture23 of'the core 19, in order to properly position the core 3 withrelation to the dies 1 and 2.

It will thus be seen that if the compression lever of the machine (whichis not here shown) is given the usual quick hard pull the molten metalfrom the cylinder containing the metal will be forced into the lower diethrough the passages 7 and8, then into the crank pin bearing of theconnecting rod 9 around the portion 21 of the core 3 and up into theupper'die around the cylindrical portion 14 of the core 3 where themetal is restricted and deflected in its path by coming into contactwith the stepped portions 1501 the core and'the stepped portions 13 ofthe die 1.

Before] the metal reaches the largest stepped portion of the core anddie it usually becomes chilled and forms a seal.

The section 10-10 adjacent the upperis always found in the cylindricalwall 26 Figs. 6 and 7 of'the drawings.

most stepped portion 13 are cutaway as illustrated at 24 to provide apassage way for the escape of the air which is in the space surroundingthe core 3. y

From an inspection of F igs.16 and 7 of the drawings, which shows thecompleted babbitted bearing removed from the connecting. rod bearing,and an inspection of Fi 8 of the drawings which illustrates thebabbitted hearing as it leaves the upper and lower dies, the same isshown provided in Fig. 8 at one end with runners 25, and at its upperend with the cylindricalwall'26,

' cylindrical stepped for the molten metal. I V V The porous or spongypart of the metal and the stepped portions 27 which, of course, is to beunderstood are to beremoved as well as the runners 25, in order to formthe completed bearing as illustrated in i It will thus be seen thatbythe employment of the two dies and the core,"the upper die beingprovided with a plurality of stepped portions corresponding with asimilar pluralityof stepped portions formed on the core, I am enabled toprovide a stepped passage way for the metalwhich as it enters thepassage ways in the lower die is forced around the core,therebyexpellingthe air from around the core and filling up the air stepped portion ontothe other, until it 110.

reaches the uppermost stepped portion where it is chilled and forms atight seal.

7 Experience has demonstrated that the organization abovegdescribed is ahighly efficient one, and while I have shown the preferred embodiment ofmy present invention,

I do not wish to be limited to the exact details of construction shownand described,

as obvious modifications thereof, not involving the exercise ofinvention, may be made by any skilled mechanic, and such departures fromwhat is herein set forth, I consider within the scope and terms of myclaims.

metal and the upper die being provided formed on the core to formstepped portions for the metal in the a stepped passage way upper die.

2. A babbitting apparatus comprising upper and lower sectional dies, amovable core engaging With said dies, the upper end of which is providedwith stepped por tions, the lower die being provided with passage Waysfor the molten metal, and the upper die being provided with steppedportions corresponding with the stepped portions formed on the passageway for the metal in the upper die.

3. A babbitting apparatus comprising upper and lower sectional dies,core engaging with said dies, the upper end core to form a stepped amovable of which is provided with stepped portions, the lower die beingprovided with passage ways for the molten metal, and the upper die beingprovided with pads to engage with said core forming vents and furtherprovided with stepped portions, and the upper die being provided withstepped portions corresponding with the stepped portions formed on thecore to form a stepped passage way for the metal in the upper die.
